SPECIFICATION forming part of Last. Patent No. 53,249, dated July 10,1900.

Application filed December 13,1899. Serial No. 740,172. No model.)

To all whom it may concern:

Be it known that LGEORGE FRANCIS KUETT, a citizen of the United States,and a resident of Paterson,in the countyof Passaic and State of NewJersey, have invented certain new and useful Improvements in Looms, ofwhich the following is a specification.

My invention relates to narrow-ware looms, and more particularly to thattype wherein [O the filling is inserted by means of fillinginsertingneedles which are reciprocated through the sheds to lay the filling inthe form of loops. In order that the filling-inserting needles may leavesuch loops in their respective sheds as they are withdrawn, it has beenproposed to provide a filling-loop-engaging needle at the side of eachset of warps opposite that into which the inserting-needles first enterand that the loop-engaging needles shall engage and hold the loops andyet free them to the action of the reed at the time of beatup. Suchloop-engaging needles have been given a reciprocation in a directionsubstantially at right angles to the plane of the warps.

This movement of the needles is liable to cause injury to thewarp-threads during reciprocation by forcing the needles into the warp,for which reason it has been necessary to so position the needles thattheir paths of movement would be some distance from the edge of thewarps. When so positioned, the loop-engaging needles have produced adefective selvage on the fabric owing to the fact that loops of fillinghave been formed 5 projecting from the edge thereof, or if the needleshave been withdrawn from the loop prior to the beat-up and an attemptmade to draw the loops into the line of the selvagewarps an unevenposition of the loops has resulted, which has been as objectionable inthe finished fabric as the projecting loops.

Although the advantages of this style of loom for weavingnarrow fabrics,such as ribbons and the like, have been recognized, yet the 5 defectiveselvage produced thereby has preeluded its general adoption.

It is the object of my invention to overcome these objections in thistype of-loom and to provide a construction that will produce a uniformand even selvage; and to this end my invention consists of the parts andcombinations, as will be hereinafter more fully described, anddefinitely pointed out in the claims.

In the drawings, Figure 1 is a sectional side elevation of so much of aloom embodying my invention as needed for the purpose of eX- planation.Fig. 2 is a plan view of one end of the same. Fig.3 is a side viewlooking in the direction of the arrow of the parts shown in Fig. 2. Fig;4 is a sectional detail showing the position of parts as the lay ismoving backward from the point of beat-up and the filling-insertingneedle'is about to enter the. shed. Fig. 5 is a plan view of the partsshown in Fig. 4 with the tension and take-up omitted. Figs. 6 and 7 areviews similar to Figs.

4 and 5, respectively, with the lay in its extreme backward position andabout to move forward for the beat-up, the filling-inserting 7o needlepassed fully through the shed, and the filling-loop-engaging needlerising to engage the filling-loop. Figs. 8 and 9 are views similar toFigs. 6 and 7, respectively, with the lay moving forward, thefilling-inserting needle retreating from the shed, and thefilling-loopen gaging needle holding the filling-loop. Figs. 10 and 11are views similar to Figs. 8 and 9, respectively, with the layapproaching the fell of the fabric and the tension on the filling 8opulling the loop-engaging needle to the edge of the warp. Figs. 12 and13are views similar to Figs. 10 and 11, respectively, with the lay just inthe act of beating up and the filling-loopengaging needle drawn againstthe reed and the edge of the warp. Fig. 14 is a diagrammatic view, infront elevation, in the direction of the arrow, Fig. 13,showing thefillin g-loop-engagin g needle yielding to the edge of the fabric underthe tension of the filling. Fig. 15 is a view in perspective of one form'1 of take-up for the filling. 'Fig. 16 is a like view of a tensiondevice for the filling, and Fig. 17 is a perspective View of one form offilling-loop-engaging needle and itssupport. 5

The loom-frame A, the lay B, oscillating from the frame at C, thecrank-shaft D, crank E, the connecting-rod F, and the breast-beam G areor may be of any usual or desircdconstrnction.

Mounted upon'the lay B in any usual manner is the reed a which may beformed in ICO sections corresponding to the number of fabrics desired tobe woven at any one time, and mounted to slide upon the lay are twofillingneedle carriers ct a The number of such carriers may obviously bevaried; but in this embodiment of my invention I have shown two for thepurpose of inserting loops from opposite sides of the warps. Thesecarriers receive reciprocating motion from the cams J K on shaft Lthrough the arms or leversM M, pivoted at M M and connected by the linksN N to the said carriers, the shaft L and connected cams being drivenfrom the crank-shaft through gearing H and I. In the present instance itwill be noticed that the cams J K are so timed by adjustment on theshaft L that they reciprocate the carriers cta alternately to insertfilling first from one side and then from the other side of the warp,

as will more fully appear. It is obvious, of course, that by adjustmentof the cams the carriers may be made to reciprocate simultaneously, orone carrier might be thrown out of operation altogether.

Mounted upon the lay 13, preferably in the rear thereof, are brackets 00 provided with guiding-perforations c for the rods or bars c andconnected to the rods or bars 0 c is a frame 0, extending, preferably,the width of the loom. The bars 0 extend below the lower bracket 0 andare connected to a moving part of the loom in order to impart to theframe 0 a rising-and-falling movement. In the present instance the bars0 are jointed at c to a connecting-rod 0 which has an adjustableconnection with a lever 0 to which an oscillating motion is imparted bythe eccentricc on crank-shaft D through the eccentric-rod c". It will beevident from this construction that as the crank-shaft revolves the layis reciprocated in the direction indicated by the arrow, Fig. 1, andthat the frame 0 is caused to rise and fall with respect to the lay.

The frame 0' carries a series of brackets d, secured thereto in anydesired manner, as by the screws d, the upper end (1 of the brack etsbeing turned at an angle and slotted at (i Fig. 17. At one side of theslot 61 there is adj ustably secured by a pin d and slot (1 anadjusting-arm (1, having an end al turned to cross the slot, whereby thelength of the slot may be adjusted as desired. Near its lower end thebracket (1 is provided with lugs d to which is pivoted a block 01 bymeans of the pin d This block 01 is perforated to receive the shank of afilling-loop-engaging needle 0, which also passes through the slot d inwhich it may move, the block (Z by its weight serving to hold the needleagainst the outer end of the slot. To assist the block in holding theneedle in this position, I may provide a spring (1, though this is notalways necessary.

The needles care made, preferably, of yielding material and are securedupon the frame 0 so that their paths of movement under reciprocation ofthe frame will clear the edges of the warp and avoid injury thereto, aswill clearly appear-from Figs. 5, 7, 9, and 13.

Secured, respectively, to the needle-carriers a 01?, preferably byadjustable connections 19 are the filling-inserting needles I) 17,arranged in pairs and adapted to insert filling from opposite sides ofthe sets of warp. It is to be understood that one needle of each pairmight be omitted, if desired, and the filling introduced from one sideonly of the warp. Each filling-inserting needle is preferably providedwith an eye 12 through which the filling leads on its way from thesource of supply to the fabric. Such supply consists of a large mass ofyarn, preferably in the form of a conical cop or bobbin, from the end ofwhich the yarn orfillingis drawn as needed.

In operation the filling-inserting needles carry loops of the fillingthrough the shed, and the filling-loop-engaging needles rise to engageand hold the loops of filling to prevent their withdrawal as theinserting-needles recede. It is necessary, however, in forming a perfectselvage that the loop-engaging needles shall not only hold the loopuntil the moment of beat-up, but they must carry said loops close to theedge of the warp, and this I have provided for by making thefilling-loop-engaging needles yieldable toward the edge of the warpunder the stress of the tension and take-up devices, which will now bedescribed.

Mounted in suitable relation with the source of supply, as the spool orbobbin .9, Fig. 4L, is a tension device, preferably one for eachfillingyarn, which continually exerts a retarding influence to themovement of the yarn or filling from the spool or bobbin. This tensiondevice may be of any desired construction; but I have shown it asconsisting of two blocks tt,hinged together at t t and each providedwith a series of eyes or guides t, staggered with relation to eachother, as will clearly ap: pear. One of these blocks maybe fixed and theother be acted on by a series of weights to, attached to a cord :5which, passing over a suitable guide-pulley t and attached to'themovable block at F, tends to normally separate the eyes or guides 6 andthus exert a restraining influence on the passage of the yarn or fillingthrough the eyes or guides.

In proximity to the tension device is the take-up, the purpose of whichis to recover the slack of yarn as the filling-inserting needle retreatsfrom the shed and, in connection with the tension device, to pull theloop-engaging needles close up to or against the warp-threads at or justprior to the beat-up, so that when the loop-engaging needle frees thefilling-loop the latter will be held in position by the reshedding ofthe warp, and thus insure a perfect and uniform selvage. The take-updevice consists of a frame f, f, and f to the flat bar f of which arepivoted at f f the take-up arms f f guided at their frame and havingthread-eyes f adjustable lengthwise thereon. Near their pivoted ends thearms f are connected to the springs j", which are secured to the flatbarf by means of the adjusting-clamps f f as will clearly appear fromFig. 15. Suitable yarn-guiding eyes f f preferably formed of somevitreous material, are provided in the curved portion f and flat barffor the passage of the yarn. It will be noticed that the take-upcapacity of the armsfmay be varied either by adjusting the yarn-guideeyes f on the arms f or by sliding the clamps f nearer to or fartherfrom the pivots of the arms to thereby vary the tension of the springs fWhile I have shown and described this as my preferred form of take-up,it is to be understood that my invention is not limited thereto, as anyform of take-up that will act to recover the slack yarn or filling andcooperate with the tension device to pull the filling-loop'engagingneedles against the warp is within the scope of my invention.

Having thus described the structural embodiment of my invention, thoughwithout intending thereby to limit myself to the particular means setforth, the operation thereof will now be described in connection withone filling-inserting needle and one filling-loopengagingneedle througha complete cycle of their movements, it being understood that the otherneedles with which the loom maybe equipped act in the same manner.Particu- 'lar reference may be had to Figs. 4: to 14, in-

clusive. The parts being in the position indicated by Figs. 4 and 5,with the lay on its backward movement from the fell of the fabric andthe shed being formed, the filling-loop engaging needle 0 is in itslowest position and the filling-inserting needle 7) on the opposite sideof the warp is about to move into the shed. At this time the take-uparmsf' f are well separated and there is no slack in the filling. As thelay reaches its rearmost position the filling-inserting needle haspassed through the shed, drawing the take-up arms f f together and asupply of filling from the spool or bobbin S through the tension device,and the parts assume positions indicated in Figs. 6 and 7,with thefilling-loop-engaging needle 0 raised into the angle formed in thefilling near the end of the inserting-needle Z). (See Fig. 6.) The laynow starts to beat up and the filling-inserting needle Z) commences itsretreating movement, leaving the loop of filling engaged by the needle 0and producing some slack in the filling I, which is taken up by thearmsf f (see Fig. 8,) while the tension device acts as a clamp toprevent further supply of filling. In the continued forward movement ofthe lay the filling-inserting needle I) is entirely withdrawn from theshed, and increased tension is thus exerted on the filling sufficient todraw the filling-engaging needle 0 against the warp-threads,\vhere, withthe increased resistance thus offered the needle against furtheryielding, it remains as the lay approaches the fell. (See Figs. 10 andneedle 0 firmly against the warp--a position i it maintains until themovement of 'beat-up and the shed has been changed.

It will be noticed that the filling-loop-engaging needle 0 is not onlylocated well outside the edge of the warp to obviate liability of injurythereto during its rising-and-falling movement, but it is also carriedsome distance in front of the reed co -in order that thefilling-inserting needle I) may pass between it and the reed andproperly deliver the loop. Since the loop-engaging needle 0 holds theloop of filling until the moment of beat-up, provision must be made forpermitting the said needle to yield toward the reed, and this has beenprovided in one form of my invention by mounting the said needle in thebracket (Z by a yielding or flexing connection, as above described. Itis desirable under some conditions of yarn or filling that the loop-engaging needle shall be adjusted or regulated in its movement toward andfrom the reed in order to properly position the fillingloop at the fellof the fabric, and this has been accomplished by the adjustable plate (Zabove set forth in detail.

The provisions for permitting the loop-en gaging needles to move oryield toward the reed come into operation particularly as the layreaches the fell, as shown in Figs. 12,13, and 14. This occurs as theshed is changed, which firmly binds the filling to place and preventsthe take-up devices from drawing the filling-loop within the warp. Theframe 0 is then lowered and the filling-loop-engaging needle iswithdrawn from the loop and the parts assume position as indicated inFigs. 4 and 5.

From the foregoing it will be observed that while thefilling-loop-engaging needles are all mounted on the same frame and riseand fall collectively and together in the operation of the loom, yetthey are separately and individually movable not only toward and fromthe reed, but also toward and from the warps. Such individual movementmay be secured in a variety of ways, as will be evident to one skilledin the art; but I have preferably formed the needles of light flexiblematerial to permit movement or flexure toward the warp under tension ofthe filling and provide for their movement to ward and from the reed bya flexible mounting for each needle in addition to its elastic oryielding character.

Manifestly the structural details of the loom can be considerably variedwithout departure from the spirit of the invention. The essentialcharacteristic of my invention is that the filling-loop-engaging needlesin addition to the usual reciprocatory movement by which they enter andquit the loops have or are capable of two other and distinct motions-theat the edge of the warps at the time the reed approaches the fell of thecloth and the loops are about to be beaten up. In their rising movementit is necessary, as hereinbefore pointed out, that the needles shallclear the edge of the warps to prevent injury thereto, and the preferredway of effecting this result is to mount the needles well outside of theedge of the warps, as herein illustrated. What is e'ssential,however, inthis respect is that the point of the needle when it reaches the planeof the warp shall be well to one side of the edge of the warps, and thisresult obviously can be obtained in a variety of ways as, for example,by bending or curving the upper portion of the needle outward or bysetting the needle diagonal or slanting with its point directed outsidethe edge of the warps; but in every instance that part of the needlewhich at the time it is at the plane of the warp stands normally at adistance from the edge of the warps must be yieldable toward the edge ofthe warps to permit the needle to be withdrawn from the loop withoutpulling out the latter.

Having described my invention and the best way now known to me forcarrying the same into effect, what I claim as new, and desire to secureby Letters Patent, is as follows:

1. In aloom, the combination, substantially as hereinbefore set forth,of the following ele ments: a lay, a reed mounted thereon, afilling-inserting needle movable lengthwise of the lay, afilling-loop-engaging needle, means for reciprocating it in a pathtransverse to that of the filling-inserting needle, and provisions formoving said loop-engaging needle toward the reed and the edge of theWarp.

2. In a loom, the combination, substantially as hereinbefore set forth,of the following elements: a lay, a reed mounted thereon, afilling-inserting needle, a tension device, a take-up interposed betweenthe tension device and filling-inserting needle, and a fillingloop-engaging needle adapted to yield towardthe reed and the edge of the warp.

3. In a loom, the combination, substantially as hereinbefore set forth,of the following elements: a lay, a reed mounted thereon,filling-inserting needles for inserting filling into the warp fromopposite sides thereof, tension devices for the filling, take-upsinterposed between the tension devices and filling-inserting needles,and filling-loop-engaging needles yieldable toward the reed and the edgeof the warp.

4. In aloom,tl1e combination, substantially as hereinbefore set forth,of the following elements: a lay, a reed mounted thereon, a series offilling-inserting needles, tension devices for the filling, take-upsinterposed between the tension devices and filling-inserting needles,and a series of filling-loop-engaging needles collectively movable toengage and quit the filling and individually movable toward and from thereed and the edge of the warp.

In testimony whereof I have hereunto set my hand this 12th day ofDecember, 1899.
